Description
Technical field
The utility model relates to the structure parts of battery, relates in particular to the radiator structure of lithium electronics electrokinetic cell.
Background technology
The electric core of the lithium-ion-power cell of prior art is an electric core, and gross thickness is 50mm, because electric core thickness problem, the heat of core is difficult for shedding, cause the temperature field skewness of battery, electric core center temperature is apparently higher than near the temperature at housing place, thereby influences the performance of battery.
Lithium-ion-power cell has characteristics such as energy height, good cycle and self discharge be low, has become the leading power supply of hybrid vehicle and electric motor car.In order to make full use of and bring into play the advantage of lithium ion battery, overcome the shortcoming of its existence, the government of each major country of the world, automaker and relevant scientific and technical personnel pay much attention to the research of lithium-ions battery big capacity, high power power, and its industrialization is also pushed ahead.The heat dissipation problem of lithium ion battery self has caused very big threat to the fail safe of battery, and the performance of battery is also had very big influence.Inside battery reaction heat comprises reaction heat, polarization heat, side reaction is hot and Joule heat, Ni-MH battery is because the aerobic air elutriation goes out, can react with hydrogen inevitably, generation side reaction heat, and concerning lithium ion battery, this part heat is almost nil, therefore can only consider remaining polarization heat, side reaction heat and Joule heat.Battery temperature is reduced gradually by middle mind-set edge, continuous discharge under 0.5C and 1C multiplying power, battery central point temperature does not surpass the battery normal temperature upper limit, can guarantee battery continuous discharge in normal temperature range, but continuous discharge under the 2C multiplying power, battery central point temperature rise meeting surpasses the cell safety temperature upper limit.
The temperature characteristic of lithium-ion-power cell under different discharge-rates carried out numerical analysis calculating, the result shows, continuous discharge under the high magnification, and battery temperature can continue to raise, finally can surpass the battery temperature upper limit, can have a significant impact the useful life and the performance of battery.This causes in the hybrid vehicle actual motion, is severely limited as the battery continuous discharge time under the high-power operating modes such as climbing, speed-raising, and the power output of battery is also had very big loss.Therefore, lithium-ion-power cell has all adopted the structure of outside heat radiation to dispel the heat in design, as shell fin structure etc.But adopt outside radiator structure also not obvious, especially can not come out the high heat in the middle of the electric core, can not satisfy people's requirement the effect that lithium-ion-power cell dispels the heat.
The utility model content
In view of there is above-mentioned many disadvantages in prior art, the utility model provides a kind of radiator structure of the lithium electronics electrokinetic cell that in time heat transferred of electric in-core portion is come out, and can improve the useful life and the performance of lithium-ion-power cell.
The utility model adopts following technical scheme to realize:
The radiator structure of lithium electronics electrokinetic cell, comprise the first electric core, barrier film and adhesive tape, it is characterized in that, also comprise the second electric core and a heat conduction baffle, the both sides that described heat conduction baffle is relative are extended two respectively in the opposite direction and are parallel to each other and all perpendicular to the flanging of heat conduction baffle body, and the described first electric core and the described second electric core are fitted with the two sides of heat conduction baffle respectively.
Further, described heat conduction baffle is that thickness is the aluminum heat conduction baffle of 0.5mm.
The utility model possesses following useful technique effect:
The electric core of prior art owing to blocked up cause dispelling the heat bad, and the utility model changes single core strueture of prior art into two core struetures, and in two electric core faying faces, add an aluminum heat conduction baffle, the heat that directly electric core is difficult for the center of heat radiation conducts out, reduces the heat of battery center.Solve the lithium-ion-power cell problems of excessive heat, guaranteed security of lithium-ion-power cell.
